Why doesn't Apple add a feature that stops charging automatically after reaching 100% charge? This is a very important feature and should be available in devices from a leading company like Apple.
You're missing the point.
Ignore for the moment that the battery has to stop charging at 100%... it can't take any more power and therefore charging has to stop.:)
The main point is that once the battery is full, the charging stops. Whether you're using wired or wireless charging, the phone and the charger communicate between each other. Indeed, when you first connect (either wired or wireless), the phone negotiates with the charger to set power rates, then the charger kicks in. When the battery is full, the phone stops charging and signals to the charger to stop.
Now, the phone has a natural 'vampire drain' that keeps the systems ticking, so over time that 100% will drop, but the charger will remain off until/unless the phone's battery level drops below a certain threshold (98% comes to mind, but I might be wrong), at which point it signals to the charger to start again. Maybe that's what you're concerned about? For that, Apple added 'Optimized Battery Charging' in Settings -> Battery -> Charging which delays the charging start such that it finishes in sync with your typical rise time. This limits the vampire drain 'top-off' and should be used if you're concerned... although it's an imperfect system if you have an irregular schedule.

The just means your device is connected to power. The actual charging is managed by the Battery Controller that is built into the battery. Your battery is not being overcharged.
No, your iPhone should not be turned off when fully charged as you will still want to have your iCloud backups run and not miss Notifications or Alarms because your phone has been shut off.
You can also use Charge Limits where charging will stop at set limit points where you will see no change in the icon. It will no longer charge until it has been depleted by 5%.
Your iPhone will charge to within a few percentage points of your chosen limit and then stop charging. If the battery charge level drops more than 5 percent while connected to power, charging will resume, again charging to within a few points of your chosen limit.
About Charge Limit and Optimized Battery Charging on iPhone - Apple Support
Your iPhone does automatically stop charging at 100%. While it may seem like it is still charging by the charging battery icon, it actually is not letting in any more charge to the iPhone. It will only resume charging after it drops a few percentage points.

Yes it does stop charging! The power indicator you see on your screen means the phone is plugged into power. The charging is managed to prevent overcharging the battery.
All Apple devices manage charging automatically. There is nothing that you need to do.

I say that the charging should be completely stopped after reaching 100%, even if I did not disconnect the plug, and I saw this feature in phone manufacturers, below the level of Apple, and not even at the level of competition with Apple. Is it possible that Apple cannot? to do it?
Therefore, Apple devices should include this feature, when charging is complete, charging should be automatically turned off and power off as if it is not related to charging.
